Write an example conversation that led to this. This: From here, we note that the volume change formula_23 due to a flux of vacancies diffusing from a source of area formula_24 is the vacancy flux formula_25 times atomic volume formula_11: formula_27 Where the second equality follows from the definition of strain rate: formula_28. From here we can read off the strain rate: formula_29 Where formula_30 has absorbed constants and the vacancy diffusivity through the grain boundary formula_31.
Preceding conversation: DIALOG:
What is the difference between a vacancy and an omission?
- Therefore, a vacancy flux exists between the poles and equator of the grain.
- What is the vacancy flux?
- The vacancy flux is given by Fick's first law at the boundary: the diffusion coefficient formula_17 times the gradient of vacancy concentration.
- How do you find the gradient of vacancy concentration?
- For the gradient, we take the average value given by formula_18 where we've divided the total concentration difference by the arclength between equator and pole then multiply by the boundary width formula_5 and length formula_20. formula_21 where formula_22 is a proportionality constant.
